Dry Age-Related Macular Degeneration (ARMD)


Introduction Age-related macular degeneration (ARMD) is a leading cause of vision loss among older adults. The condition is characterized by the gradual deterioration of the macula, a small area of the retina responsible for central vision. There are two main types of ARMD: dry and wet. Dry ARMD, also known as non-exudative ARMD, is the more common form of the condition and is caused by the accumulation of debris known as drusen under the retina.

Symptoms 

Dry ARMD typically progresses slowly and may not cause significant vision loss in its early stages. However, as the condition progresses, individuals may experience symptoms such as difficulty reading, recognizing faces, or performing other tasks that require fine vision. They may also experience a gradual loss of central vision and a reduction in the ability to see colors.

Risk Factors 

The most significant risk factor for developing dry ARMD is age. Other risk factors include a family history of the condition, smoking, high blood pressure, and exposure to UV light.

Diagnosis 

A comprehensive eye exam is typically used to diagnose dry ARMD. This exam may include tests such as a visual acuity test, a dilated eye exam, and a fundus photography.

Treatment 

There is currently no cure for dry ARMD, and treatment options are limited. However, there are several measures that can be taken to slow the progression of the condition and help manage symptoms. These include:

  • Eating a healthy diet rich in fruits and vegetables
  • Taking vitamins and minerals, such as vitamins C and E, beta-carotene, and zinc
  • Not smoking
  • Using protective eyewear to reduce exposure to UV light
  • Monitoring for changes in vision and seeking prompt medical attention if symptoms worsen

Prognosis 

The prognosis for dry ARMD varies depending on the severity of the condition and the individual's age and overall health. In some cases, the condition may progress slowly and cause only mild vision loss. In others, it may progress rapidly and cause severe vision loss.

Conclusion 

Dry age-related macular degeneration (ARMD) is a progressive condition that can cause significant vision loss in older adults. While there is currently no cure, there are several measures that can be taken to slow the progression of the condition and help manage symptoms. Individuals at risk for dry ARMD should have regular eye exams and take steps to reduce their risk factors.

Mosquito eyes

 Mosquitoes, like many other insects, have compound eyes. Compound eyes are made up of numerous individual photoreceptor units called ommatidia. Each ommatidium consists of a lens, a cornea, a crystalline cone, and a light-sensitive receptor cell.  Mosquito compound eyes are typically large in proportion to their body size and are positioned on the sides of their head. They have a spherical shape and provide mosquitoes with a wide field of vision, allowing them to detect movement in different directions.  The compound eyes of mosquitoes are designed primarily for detecting changes in light intensity and movement rather than forming detailed images. Each ommatidium captures a small part of the overall image, and the mosquito's brain processes the input from multiple ommatidia to form a composite picture of its surroundings. Mosquitoes are attracted to certain stimuli such as heat, carbon dioxide, and chemicals in human sweat, which help them locate potential hosts for blood meals. T

Contact lens parameters

 Contact lenses are medical devices that are worn directly on the cornea of the eye to correct vision or for cosmetic purposes. There are various parameters associated with contact lenses that are important for fitting and prescribing the right lenses for individuals. Here are some common parameters: 1. Power (Refraction): Contact lenses are available in different powers to correct nearsightedness (myopia), farsightedness (hyperopia), astigmatism, and presbyopia. The power is measured in diopters (D) and can be positive (+) or negative (-) depending on the type of vision correction needed. 2. Base Curve (BC): The base curve determines the curvature of the contact lens. It is typically measured in millimeters (mm) and represents the curvature of the inner surface of the lens. The base curve is chosen to match the curvature of the cornea for proper fit and comfort. 3. Diameter (DIA): The diameter of a contact lens is the measurement across the lens from edge to edge. It is usually measur

Base Curve of contact Lens

The base curve of a contact lens refers to the curvature of the back surface of the lens. It is measured in millimeters and is one of the main characteristics of a contact lens. The base curve is important because it determines how well the lens will fit on the eye. A lens with a base curve that is too flat may not conform to the shape of the eye and may cause discomfort or irritation. On the other hand, a lens with a base curve that is too steep may be difficult to insert and remove and may cause lens dislocation or other problems. To find the right base curve for a contact lens, an optometrist will measure the curvature of the eye using a tool called a keratometer. This instrument measures the curvature of the front surface of the eye (the cornea) and helps the optometrist determine the appropriate base curve for the lens. In addition to the base curve, other factors that can affect the fit and comfort of a contact lens include the diameter of the lens and the material o
